I DON'T have a virus, because I ran AdAware and Norton several times, and they haven't found any viruses, yet my hard drive space keeps decreasing slowly. I'm losing like a gigabyte every 5 minutes. I don't have a virus like I said! What's up with this?!

I can't stand weeaboos and people who keep badmouthing dubbed anime and say it sucks.

Between windows updates, the various temporary folders that get generated by running programs, browser cache, etc... there will be some decrease over time...but not that much.

WinDirStat should help you tack down the source.

This reminds me of a logging problem that I was encountering with ZoneAlarm (firewall, the free one) a while back. I think the file was tvdebug.log, and I think it was eventually fixed in an update...that or I just turned off logging.

Wow, WinDirStat is awesome. Apparently music comprises most of my hdd, which isn't surprising, but it's cool to see everything in perspective. Diablo 3 already takes up more space than Skyrim, and it's not even released. :O

WinDirStat or other similar apps are great! I found out that Windows Media Player was creating thousands of duplicate thumbnails for music/images/videos that resided in the user library folders. It was like 8 GB of thousands of tiny thumbnails. After deleting them I had to use some crazy work around to prevent WMP from indexing the library folders, because if you delete it from the WMP library, it deletes the library folder itself.

As far as losing a gigabyte every 5 minutes; do you have any applications open when you notice this? Adobe apps like Photoshop and Premiere have temp files and/or generate additional cache files when importing/modifying media. Maybe you have an over aggressive backup program creating snapshots? If you're using Vista/7 the Resource Monitor and checking the disk tab might help when you notice it occuring.

The thing is I basically don't, but since WMP automatically uses the Music/Pictures/Video libraries during the random times it would get open (usually for DVD playback and random testing) it would start its indexing and thumbnail generating. With over 140,000 files in those 3 libraries and it's duplicate thumbnails for some reason it got out of hand. You would think it would as easy as going to Manage Libraries and removing those folders from the list. However, removing the library folder in WMP actually removes the library from the system entirely. So to keep those libraries and use WMP occasionally I had to disable the indexing service and make its databases empty and read-only. Personally I use iTunes for music/podcasts since I own an iPhone. If I was rolling a lossless audio collection I'd probably use Foobar, but high bitrate AAC/MP3 is 95% of my library. So even if you don't use WMP but it has been opened from time to time it may be generating a lot of redundant files.
